Design and Application Research of Stator Winding Based on Single Bar Connection
For large AC synchronous machines with specific speeds,the matching problem between poles of stator winding and the number of symmetrical balanced branches can be solved through a single bar connection method.This article analyzes the winding symmetry,and a quantitative evaluation method for symmetric balance of parallel branches has been proposed.At last the effectiveness of the analysis method was verified through the application of FE method analysis and machine testing.
